Tafsiran Ayub 16:1: Malbim

Job does not reply at once to the resolution of the question of the prosperity of the wicked advanced by Eliphaz, nor to the thesis Bildad adopts on his issue, preferring to wait until all three of his companions have addressed the subject. He then answers them all (in Chapter 21) in comprehensive response that rebuts everything they had said on the subject.

Nor does he react to Eliphaz's repetition of the claim he had made in his first oration, namely, that he had received a prophetic vision concerning the suffering of the righteous, as he had already replied to it at the time. He just rebukes him for repeating himself and for adding nothing new, as though all he wanted to do was to drown him with words, which is not the way of the wise (Ch.16:2-5).
